During upload the BackupManager stores the file using the original name without sanitization. When a restore request later references that file, the host interprets the special characters and executes them, giving the attacker control over the server.", "risk_and_exploitability": "The severity is high with a CVSS score of 8.1, but the current EPSS score is below 1% indicating a very low probability of exploitation in the wild. The vulnerability does not yet appear in the CISA KEV catalog.

The attack vector is therefore likely a trusted environment or an internal network where legitimate users or compromised accounts can interact with the backup feature."}}}}, "created": "2026-01-23T10:27:31.196762+00:00", "updated": "2026-04-18T03:30:25.916419+00:00", "vendors": ["runtipi", "runtipi$PRODUCT$runtipi"]}
